Anti-COQ4 antibodies are used in the immunodetection of the protein coenzyme Q4. In humans, the canonical protein has a reported length of 265 amino acid residues and a mass of 29.7 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is found to be widely expressed, but at high levels in the liver, lung and pancreas. A member of the COQ4 protein family, COQ4 is a known component of the coenzyme Q biosynthetic pathway. The COQ4 gene has been associated with the disease, Coenzyme Q10 deficiency. Synonyms for this target antigen include COQ10D7, ubiquinone biosynthesis protein COQ4 homolog, mitochondrial, coenzyme Q biosynthesis protein 4 homolog, coenzyme Q4 homolog, and CGI-92. COQ4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of COQ4 antibodies have been mentioned in research publications and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
